Introduction

In this tutorial you will learn how to use one water flow sensor with an Arduino board.

The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.

We are super excited to welcome two new boards in the codebender family!
